  1. Hi, forgive me if this isn't the right forum for this, but ultimately, I'm working towards authoring a BDXL disc with an NTSC VHS source that I ran through an AI upscaler that upscaled the resolution by x2 (so currently 1440x960).

    After capturing my NTSC VHS in VirtualDub at 720x480, and applying some moderate restoration via Avisynth and an AI model that was designed for restoration, which also happened to upscale the resolution by x2, I'm up to about 76gb for my AVI. I'd like to keep it that way, I'm not interested in lowering the file size. So I'm planning on authoring to a BDXL disc.

    With that said, how would the 1440x960 resolution work on a blu-ray when being played in a blu-ray player on a TV? Would I have to do any work on the resolution so that it would display correctly? Would the aspect ratio be completely messed up?

    You should be interested in reducing the filesize , because authored BD disc - playable in a BD player - has restrictions on codecs, bitrates. They can only read from optical disc and transfer into the buffer at a given rate

    Read up on what is blu-ray , bitrates, and restrictions in terms of encoding, settings, VBV buffer. There are many threads covering this, and what is compliant. Otherwise it won't author correctly, won't play correctly , will stutter or won't play at all

    Authored Blu-ray also has restrictions on resolutions and frame rates. If it was 23.976p, you would use a 1920x1080 frame . A 4:3 perfect AR source would be pillarboxed . 1440x1080 with 240px left and right. You might have to adjust that a bit depending on if you cropped borders or what the true AR of the image is

    Ah okay gotcha, yeah I can go ahead and do some independent research then. Appreciate the heads up! I have no idea what I'm doing lol. Yeah it's 23.976 fps, so then if I maintain the 1440x960 resolution, it'd be letterboxed/bordered to achieve 1920x1080?

    1440x960 is double of 720x480 . But NTSC VHS is not "square pixel" format. The AR is most likely wrong if you keep it 1440x960 and both

    pillarboxed,letterboxed in a 1920x1080 frame . ie. 1440x960 is the wrong square pixel dimensions - you have to scale width, height, or both

    A "normal" 4:3 DVD or VHS does not display at 720x480 either.

    Also you want to crop the junk off around the frame and leave it clean after de-interlacing and before upscaling to 1440x1080, I would think Blu-ray accepts 4:3 AR in 1440x1080, doesn't it?

    1440x1080 is only supported at 16:9 for BD

    Good to know, So padding to 16:9 is a must then.

    Late reply... but you can use TMPGEnc Authoring Tool (30 days free trial) and do BR there. There's little chance you'll do it better and more BR compliant.

  9. Is your footage really 23.98p? That is very unusual for a tape source, unless you knowingly applied IVTC.

    Aside of everything else stated regarding the pillarboxing and AR, you can most likely compress it nicely to a lower filesize without hindering quality and maybe even make it fit on a standard BD50.
